Visiting Lithuania for a week in April

[u/sn0wlark]

Hello! I'm visiting Vilnius for a week this coming April from Minnesota, and I'm wondering if there are any cultural faux pas that I should avoid. Unfortunately, I am an American, and know people are tightly not fond of us. When I visit places, I try to avoid making any sort of fuss or inconvenience anyone. Travelling both as a biracial American (black and white), I know that I'll probably seem strange, but I really want to minimize any disturbances or annoyances. I'm a big history nerd and Lithuania seems both full of beauty and history.

Mainly, I'm asking for any advice on how to annoy people the least amount 😅 thanks in advance and am so sorry if this isn't the right place for this kind of post.
